DETAILED DESCRIPTION OF THE INVENTION

FIGS. 1 and 2 illustrate a pairing process for a system 100 for securely connecting a wireless device to a single access point in a vehicle. The secure connection is preferably established between a tablet computer 110 and connected vehicle device (“CVD”) 130. The CVD 130 is preferably physically connected to an on-board computer of a vehicle. The vehicle is preferably a delivery truck or a long-haul semi-truck. The CVD 130 uses a BLUETOOTH signal that is broadcast in a hidden mode, and thus the wireless network is unpublished. The tablet computer 110, having previously paired with the CVD 130, is used to “find” or re-pair with the wireless network of the CVD 130 since the BLUETOOTH settings are retained in a memory of the tablet computer 130. At block 111, the installation begins for the tablet computer 110. At block 112, a setup screen having an ESN, a power unit identification and a tablet computer serial number is displayed. At block 113, the identifications are inputted, and at block 121 they are validated. At block 114, it finds the hidden mode BLUETOOTH signal plus the password. The BLUETOOTH signal preferably comprises a MAC address for the CVD. At block 115, the processing occurs including the processing of the tablet computer setup and the verification of the power unit identification. At block 116, it connects with the default settings to the CVD 130 pairing with the default settings 131 of the CVD 130. At block 117, the tablet computer sends configuration data to the CVD 130. At block 132, the CVD 130 updates the BLUETOOTH settings and at block 133 validates the power unit to the VIN. At block 140, the CVD 130 is registered with a cloud computing service 140, and at block 142, the tablet computer is registered with the cloud computing service 140. At block 118, the tablet computer 110 sets the configured MAC address and password from the CVD 130. At block 119, the tablet computer 110 reconnects with the configured hidden mode BLUETOOTH settings. At block 134 on the CVD 130, the configured hidden mode BLUETOOTH settings include the MAC address: encrypt (power unit identification salt) and the BLUETOOTH signal is broadcast in the hidden mode. At block 122, the settings are validated on the tablet computer 110, or the tablet computer 110 and the CVD 130 utilize a traditional BLUETOOTH certificate pairing (Host and Client). Alternatively at block 122, the settings are validated on the tablet computer 110, and the tablet computer 110 and the CVD 130 utilize a traditional BLUETOOTH certificate pairing (Host and Client) as a secondary authentication. In an alternative to utilizing the traditional BLUETOOTH certificate pairing, the certificate has a second field which must be submitted for pairing and re-pairing. The second field may include the MAC address of the CVD 130. During a traditional BLUETOOTH pairing, the CVD 130 and the tablet computer 110 establish a relationship by creating a link key. The CVD 130 and the tablet computer 110 store the same link key to be paired. The tablet computer 110 can cryptographically authenticate the identity of the CVD 130, ensuring it is the same CVD it previously paired with. Once a link key is generated, an authenticated asynchronous connection-less link between the CVD 130 and the tablet computer 110 is encrypted to protect transmitted data. Block 120 is a critical error screen in which the tablet connection setup failed or the power unit identification was not verified. At block 123, a confirmation screen is shown on the tablet computer 110. At block 124, the setup is complete. At block 125, a tablet hidden mode BLUETOOTH setup re-pairing screen is shown.

As shown in FIG. 3, each of a multitude of trucks 210 a-210 d broadcast a wireless signal for a truck specific network, with one truck 210 c broadcasting a hidden mode BLUETOOTH wireless signal 225. Since the hidden mode BLUETOOTH is not published, only a driver is already in possession of the hidden mode BLUETOOTH signal can pair the tablet computer 110 with the CVD 130 of the truck 210 to which the driver is assigned. So even though the hidden mode BLUETOOTH wireless signals are being “broadcast”, they will not appear on a driver's tablet computer 110 (or other mobile device) unless the tablet computer 110 has already been paired with the CVD 130 of the vehicle 210. A driver 205 in possession of a tablet computer 110 pairs, using a signal 230, the tablet computer 110 with the wireless network 225 of the CVD of the truck 210 c, and thus the driver locates the specific truck 210 c he is assigned to in a parking lot full of identical looking trucks 210 a-d.

For example, on an IPHONE® device from Apple, Inc., the “UDID,” or Unique Device Identifier is a combination of forty numbers and letters, and is set by Apple and stays with the device forever.
